Super size me in little bits and pieces



Alvin came into the office for consultation on his cholesterol values: LDL 198 mg/dl, HDL, 43 mg/dl, triglycerides 143 mg/dl. He says that he doesn't really try to choose healthy foods but he restricts his overall calorie intake by following the Weight Watcher's exchange approach.

Every morning, 7 days a week, Alvin eats a Sausage McMuffin for breakfast. He justified this by skipping lunch to make up for the 450 calories in the Sausage McMuffin, and not eating anything until dinner.

Can this work? Can you eat foods with unhealthy ingredients but make up the excessive calories by cutting back elsewhere?

The nutritional composition of McDonald's Sausage McMuffin includes 27 grams of total fat (10 gm saturated); 255 mg cholesterol; 950 mg sodium; 31 gm carbohydrate; 2 grams fiber. In other words, it's essentially the same as butter with sugar on it--pure fat, processed wheat, with little fiber or nutritive value.

For Alvin, this is an extremely unhealthy way to eat. His lipid patterns are just the tip of the iceberg: multiple hidden factors are also at work to create heart disease, atherosclerosis in other territories outside the heart, diabetes, high blood pressure, and cancer.

I think the effects are not much different than what Morgan Spurlock achieved in his Super Size Me documentary, but in little bits and pieces. Eating at McDonald's "restaurants" three times a day yielded frightening changes in his lipids, liver function, kidney function, not to mention his appearance and the way he felt. Alvin is doing the same thing, though in less dramatic fashion.

I see this very frequently: people mimicking the experience of Spurlock, just a little at a time, with overindulgence in processed fats and starches.

When you seen a set of Mcdonald's golden arches (or any fast food restaurant, for that matter), run as fast as you can in the other direction. Such indulgences, even in small bits and pieces, still creates a mess of your health.

View from the precipice


Many people, upon first learning of their CT heart scan score, feel like they're on the edge of a sharp drop. It can feel like you're facing a vast, unknown abyss. At the bottom, all those dreaded things that can happen to you: heart attack, heart failure, hospitals, even dying.

I've encountered this "deer in the headlights" look many times. It truly can be frightening to hear that your heart scan score is 300, or 500, or whatever.

What I find truly frightening, however, is when your score prompts the usual array of misinformation commonly dispensed by physicians: "That's so bad you need a heart catheterization", "Nobody knows why people get calcified plaque", or "Reversal is impossible". All absolute bunk.

Let your fear motivate you to do something about your risk for heart disease. Aim for reversal of your coronary plaque and seek out the tools to achieve this. It is possible and, in fact, we do it all the time. I can't claim 100% success, but the majority of people who engage in an effort like the Track Your Plaque program to reverse coronary plaque succeed. Even a substantial slowing of plaque growth from the expected 30% per year is better than submitting to the conventional approach.

At the very least, get both LDL and HDL cholesterol around 60 mg/dl. This alone is a major plus in reducing the risks associated with your heart scan score. It doesn't guaranteee reversal, but it sure tips the odds in your favor.

Organic Rice Krispies?



Breakfast cereal manufacturing giant, Kelloggs, is launching a line of three cereals that will carry the "organic" designation: Organic Rice Krispies, Organic Raisin Bran, and Organic Frosted Mini-Wheats.

This reminds me of the advertisements I've seen for "fresh fried chicken", or "fresh from the can", or "contains only pure cane sugar". How about organic tobacco? Would that make cigarettes healthier?

The TV ad ends with the slogan "Childood is calling!" Oh, those marketers are a shrewd, clever bunch. I worry that they're so clever that most people will fall for these ludicrous tricks.

Don't fall for these thinly-shrouded marketing shenanigans. Organic? Who cares. These foods remain unhealthy whether or not they contain pesticide residues. Take a look at the nutritional composition: Rice Krispies, organic or not, is sugar to your body. It is the sort of food that creates pre-diabetes, diabetes, makes us fat, and fans the flames of lipoprotein patterns like small LDL, VLDL, and postprandial particles, all of which is like throwing cow manure on the weed patch of your coronary plaque.

Nuts as functional foods

Food manufacturers gave nuts a bad name when they started adding evil ingredients to them. "Party mix", "honey-roasted", mixed nuts, etc., are made with added hydrogenated oils, salt, sugar, excessive quantities of raisins, or other added ingredients that turned a healthy food--nuts--into something that made us fat and hypertensive, raised LDL, dropped HDL, and raised blood pressure.

But nuts themselves are, for the most part, very healthy foods. The very best are nuts with a brown fiber coating like almonds, walnuts, and pecans. Nearly all nuts also come rich in monounsaturated oils similar to that in olive oil. Although calorie-dense, nuts tend to be very filling and slash your appetite for other foods. I have never seen anyone gain weight by adding raw nuts to their diet. In fact, I find adding raw nuts cuts craving for sweets.

Nuts are also among the most concentrated sources of magnesium, containing around 150 mg per 1/2 cup serving. As most Americans are at least marginally if not severely deficient in magnesium, this really helps. Magnesium deficiency is a prominent aspect of "metabolic syndrome" and resistance to insulin.




Some nuts have added benefits like the l-arginine content of almonds or the linolenic acid content of walnuts. However, I think the real health "punch" comes from the fiber and monounsaturate content.

Add 1/4-1/2 cup of raw almonds, walnuts, or pecans per day to your diet and what can you expect? The effects that I see every day that are relevant to plaque control/heart scan score-reducing efforts include:

--Reduction in LDL--usually a 20 mg/dl drop, sometimes more.

--Reduction in triglycerides, especially if nuts replace processed carbohydrate calories. This may be because the fiber and monounsaturate content of nuts reduces blood sugar and the effective glycemic index of any accompanying foods.

--Modest blood pressure reduction.

--Though somewhat inconsistent, partial suppression of the dreaded small LDL particle pattern. We struggle with turning off the small LDL pattern in some people, and raw nuts can provide a real advantage.

If that isn't enough, the fiber content also makes your bowels regular.

Unless there's some reason to avoid nuts (e.g., allergy), nuts should be a part of your heart scan score reducing program. Shop around, as prices can vary wildly. I've been paying $12.99 for a 3 lb bag of raw almonds from Sam's Club, though I've seen almonds elsewhere for up to $12.99 per pound.

For additional commentary, go to one of my favorite Blogs, http://fanaticcook.blogspot.com. The Fanatic Cook's recent post, The Season for Walnuts , provides additional discussion on walnuts and the recent study showing how they improve "endothelial function". The nutritionist behind this Blog has fabulous insights into food, including the concept of "functional foods", i.e., using foods as a treatment tool. She is also unfailingly entertaining.

Can you tell the difference?

Stan is 55 years old. He feels fine, is in moderately good physical condition. His LDL cholesterol is 135 mg/dl, HDL 43 mg/dl, triglycerides 167 mg/dl, total cholesterol 211 mg/dl.

Can you tell me whether Stan has heart disease or not?

How about Charles? Charles has an LDL cholesterol of 127 mg/dl, HDL of 44 mg/dl, triglycerides of 98 mg/dl, and total cholesterol of 191 mg/dl. He is also reasonably fit and feels fine. Can you tell whether Charles has heart disease?

If you can't, don't feel bad. Neither can your doctor. But this is the folly of using cholesterol for risk prediction.

Stan's heart scan score: 0

Charles' heart scan score: 978

Look even more closely at Stan's and Charles' cholesterol numbers. Is there some fine distinction we overlooked? What if we calculated total cholesterol to HDL ratio? Or LDL/HDL ratio?

No matter how you squeeze it, shake it, beat it with a stick, you simply cannot use cholesterol numbers to predict heart disease in specific individuals. Yes, the higher your LDL cholesterol and lower your HDL, the higehr your total cholesterol to HDL ratio, the greater the likelihood of heart disease. But you can simply cannot tell in a specific individual at a specific point in time. If you've seen your doctor puzzle over the numbers, understand that he/she is trying to make sense out of something that doesn't make sense, no matter how hard he/she tries.

You simply need to measure the disease itself: get a CT heart scan, the only measure of atherosclerotic coronary plaque that you have access to.

By the way, if you haven't seen it yet, go to the Track Your Plaque website (www.cureality.com) to see the news piece reporting the American Heart Association's much overdue position statement on CT heart scanning. The AHA has finally released a statement which, in effect, provides their "official" endorsement. Blocked by political shenanigans behind the scenes for several years, the guidelines finally made it to press. The only real difference it makes to me is that my patients may finally get their heart scans paid for by insurance, once the insurance companies realize that it's getting tougher and tougher to dodge their responsibility.

Statin agents and muscle aches

How common are muscle aches with the statin drugs?

It depends on who you ask. If you ask the drug manufacturers, they will tell you no more than 2% of people who take them. They back this up with the experience in tens of thousands of people in published clinical trials.

What if we ask people who take them outside of clinical trials. How many then? I estimate, from my large experience, over 80%! In other words, muscle aches are inevitable in nearly everyone who takes them. The longer you take them, the higher your dose, the more likely muscle aches are going to be.

Why the disconnect between published data and real-world experience? I really don't know. In some instances, the differences are dramatic. The ASTEROID trial, for instance, in which Crestor, 40 mg, was given for two years, only resulted in 8% of people dropping out because of side-effects. My experience: everybody--nobody can tolerate this dose for any length of time.

Let me qualify what "muscle aches" mean. It means achiness and/or weakness, usually mild, occasionally moderate to severe, worse upon awakening and less with use. It can affect many muscles or it can involve only one. Rarely is it incapacitating but it is commonly annoying and frightening. It commonly shows up as gradually diminishing strength with exercise. Strength usually returns promptly upon stopping the offending drug.

"Rhabdomyolysis", or true muscle destruction is, fortunately, very unusual in otherwise well people. People with abnormal kidney function, diabetes, and other concurrent illnesses are somewhat more prone. But in reality, rhabdomyolysis is unusual. I've personally seen it twice, both in people sick for other reasons.

Coenzyme Q10 (CoQ10) supplementation has been a godsend for us. At least 4 out of 5 people who require statins and develop muscle aches respond favorably, but it requires 100 mg per day. The preparation must be oil-based to work, not powder in a capsule which exerts no effect. Some people get by with less; some require as much as 300 mg per day. I've had favorable experiences with the CoQ10 from Sam's Club, GNC, Vitamin Shoppe, and Life Extension (www.LEF.org).

The Track Your Plaque target for LDL cholesterol is 60 mg/dl. Many people do indeed use statins to achieve this level, the level of LDL that amplifies your chances of heart disease reversal, i.e., reduction of heart scan score. The only drawback that I'm aware of with CoQ10 replacement is cost. Beyond this, it's a benign supplement that even supplies higher energy for some people who take it.

More catheterizations would make me happy!

I received this fax today from a cardiologist seeking a position:

"I would prefer to perform as many interventions [stents, angioplasties, etc.] as possible..."

That about sums it up, doesn't it? The goal of this young man, trained in major universities including Columbia University, Harvard, and Emory, is not to pursue an avenue of investigation or healthcare that yields real answers. His goal is to perform as many procedures as possible.

This attitude is deeply ingrained in cardiologists. It's also shared by all procedural medical specialties: the drive to do more and more procedures. It's not because it does more good for the public, but it fulfills a primitive impulse to spread your influence, enlarge your territory, and--of course--make more money.

Personally, I find this impulse repulsive. The fact that this young cardiologist looking for a position is willing to make this statement out in the open demonstrates how widely accepted this attitude is. Imagine your cancer surgeon, looking for a new job, said, "I'm looking to remove as many tumors as I can."

My colleagues have lost sight of the fact that we're trying to reduce or eliminate disease, not enrich our pockets or service some primitive impulse to beat others at our game.

"I hate fish oil!"

I get this comment occasionally, usually from the fishy belching that can occur, rarely because of other crazy effects like rash, fishy body odor, etc.

In the vast majority, fish oil is a benign but wonderfully effective agent. Track Your Plaque followers know that fish oil, starting at 4000 mg per day of a standard 1000 mg capsule preparation, dramatically reduces triglycerides and thereby raises HDL, partially suppresses small LDL, and is the best agent available for reducing postprandial (after eating) abnormalities like IDL and certain VLDL fractions.

However, an occasional person (about 1 in 20) just doesn't like the effects. Are there alternatives? Fish oil packs such a wallop of beneficial effects that can not be replaced by any other single agent or lifestyle practice. For this reason, we have a number of easy strategies to enhance your tolerance for fish oil. (Of course, if your and/or you doctor determine that you're allergic to fish oil, then you should indeed avoid it; thankfully, this is rare.)

Helpful strategies include:

--Refrigerate fish oil capsules--this cuts back on fish belching.
--Take only with meals. This also may increase fish oil's benefits on suppressing after-eating lipoprotein abnormalities.
--Take an enteric-coated preparation--this delays breakdown of the tablet/capsule, making fishy belching less of an issue. Sam's Club has an inexpensive preparation.
--Take liquid fish oil. Usually orange or lemon flavored, liquid fish oil may be a faint fishy taste and odor, but usually not as prominent as the capsules. There's also less stomach upset.
--Coromega--a paste form of fish oil available at health food stores or through http://www.coromega.com. Coromega tastes fruity and comes in little squeeze envelopes.
--Frutol--Pharmax, a British company, makes another fruity fish oil that is non-oily and tastes like apricot. It's actually fairly reasonably priced, too. However, it is hard to find. The only way I know to get is to go online at www.pharmaxllc.com. You may have to actually order through a health care provider.

When using any preparation of fish oil, the best way to determine your dose is to add up the EPA and DHA content. For instance, if you use a fish oil liquid that contains 320 mg EPA and 240 mg DHA per teaspoon, you will need two teaspoons a day to achieve the equivalent of our starting dose of 1200 mg of EPA+DHA, usually provided by 4000 mg total in 4 capsules. Note that some lipid and lipoprotein disorders will require higher doses, e.g., 1800 mg EPA+DHA for high triglycerides (>200 mg/dl) or high IDL.

Sudden death in athletes

A recent report in the Journal of the American Medical Association details how a group in the Veneto region of Italy cut back on the incidence of sudden cardiac death in athletes by a simple screening program.



You can read the abstract of the article at http://jama.ama-assn.org/cgi/content/full/296/13/1593.

Although sudden death in athletes is still a rare event, it is especially tragic when it happens. In this population, the incidence was 3.6 deaths per 100,000 athletes aged 12 to 35 years. By implementing a simple screening program that involved only a physical examination and an EKG, an astounding 89% reduction in sudden death was documented.

What lessons does this hold for those of us interested in coronary plaque reversal? Beyond the obvious lesson of pointing out the great benefit of simple screening of athletes, I believe that it tells us the value of simple screening tools for heart disease in general. It is my strong belief that, if we were to implement CT heart scans among the broad population of men 40 years and over, women 50 years and over--without regard to cholesterol or other relatively lame risk identifiers--we could slash the risk for heart attack and death 90% or more. Putting CT heart scans into the hands of the public makes your coronary risk obvious. It takes the guesswork out of risk predictors like cholesterol and high blood pressure.

But heart scans are already available, you say! Yes, of course they are. But the lack of insurance reimbursement continues to be a restricting factor for many people, despite the number of lives that could be potentially saved and the money that would be saved in the long run by reducing need for major heart procedures. The continuing resistance to prevention by my cardiology colleagues and the persistent ignorance of primary care physicians also remain major impediments.

But it's getting better. You don't have to be chained by ignorance. Put your CT heart scan to good use.

My heart scan was wrong!



Tom came into the office ready for a confrontation.

Tom's wife insisted that he see me to discuss the implications of his CT heart scan score of 459. At age 50, this was clearly bad news that placed Tom in the 99th percentile (worst 1% of men in his age group).

But Tom had already undergone a stress test. There had apparently been a small abnormality, and a heart catheterization had been performed by another cardiologist. "They told me they didn't need to do anything. No stent, no ballon, no bypass, nothing!"

I asked, "Did they tell you that there was any plaque or blockages seen?"

"Yeah, but he said it was nothing. So the heart scan was wrong!"

I've been here many times before. I explained to Tom that, no, his heart scan was not wrong. All the tests he'd undergone siimply provided a different perspective on the same disease. You could say:

--The stress test, being a test of blood flow, may have been abnormal because of the abnormal constrictive behavior of arteries containing plaque, known as "endothelial dysfunction", because the inner lining of arteries (the endothelium) control the tone of the artery. Abnormal constriction in arteries with plaque is quite common.

--The catheterization simply showed that no plaque had collected in a configuration to block flow, thus no stent, etc., since flow was normal. But there was indeed plaque.

All three tests were right; none were wrong. They all provided a little different perspective on the same process. Of course, I favor the heart scan as the means to identify, precisely measure, and track the atherosclerotic plaque in your arteries. The stress test is too crude and only measures flow, the catheterization is not something you'd want to undergo year after year. Catheterization also is too crude a measure to precisely track plaque growth or reversal.

So I explained to Tom that, even though a stent or similar procedure was unnecessary, he remained at substantial risk for heart attack due to plaque "rupture". In fact, Tom's heart attack risk was 5% per year, or approximately 50% over the next decade. That is, indeed, substantial. In fact, you might say that, of the three tests Tom underwent, only the heart scan revealed his true risk.
Vitamin D: Deficiency vs optimum level

Vitamin D: Deficiency vs optimum level

Dr. James Dowd of the Vitamin D Cure posted his insightful comments regarding the Institute of Medicine's inane evaluation of vitamin D.

Dr. Dowd hits a bullseye with this remark:

The IOM is focusing on deficiency when it should be focusing on optimal health values for vitamin D. The scientific community continues to argue about the lower limit of normal when we now have definitive pathologic data showing that an optimal vitamin D level is at or above 30 ng/mL. Moreover, if no credible toxicity has been reported for vitamin D levels below 200 ng/mL, why are we obsessing over whether our vitamin D level should be 20 ng/mL or 30 ng/mL?

Yes, indeed. Have no doubts: Vitamin D deficiency is among the greatest public health problems of our age; correction of vitamin D (using the human form of vitamin D, i.e., D3 or cholecalciferol, not the invertebrate or plant form, D2 or ergocalciferol) is among the most powerful health solutions.

I have seen everything from relief from winter "blues," to reversal of arthritis, to stopping the progression of aortic valve disease, to partial reversal of dementia by achieving 25-hydroxy vitamin D levels of 50 ng/ml or greater. (I aim for 60-70 ng/ml.)

The IOM's definition of vitamin D adequacy rests on what level of 25-hydroxy vitamin D reverses hyperparathyroidism (high PTH levels) and rickets. Surely there is more to health than that.

Dr. Dowd and vocal vitamin D advocate, Dr. John Cannell, continue to champion the vitamin D cause that, like many health issues, conradicts the "wisdom" of official organizations like the IOM.

    Where I live, it's been around 10 degrees Fahrenheit for about two weeks straight. Probably too cold to lay out in a bathing suit.

    For many of us, supplementation is the only choice.

    Also, don't forget that the majority of people after age 40 have lost much of their ability to activate vit D in the skin.

    I just added his book to my wish list and it will be my next read. I am beginning to wonder why don't we seek to reach serum vitamin D somewhere between 100-150 range. Has there been any research indicating any response to these levels? Even with all the recent research focusing on vitamin D, it would be nice to understand overall health responses at varying degrees of serum content from deficiency to toxicity. We need a wider perspective to draw from.

    BTW, an update: 110 pounds and counting . . . My BMI is about to fall into the normal range and my health has never been better!

    This is an unusual thought. Sitting in front of a very warm and soothing fire last night, I was wondering how my skin reacts to the radiation, aside from the warmth and relaxation benefits.

    My level dropped 20 points when I reduced my intake from 10,000 iu/day to 5,000 /day.  I went back to 10,000 and now I'm at 63 ng/ml.  I'll stick with 10,000 iu unless I exceed 100 ng/ml.

    I wonder if there is not a missing piece to the puzzle of vitamin D deficiency in relation to adequate iodine levels.  I have appended text from the website Iodine4health.  In it Dr. Vickery noticed a connection between the two:

    ”I have also noted an apparent connection between bringing sufficient iodine to a bromine plugged thyroid, and the vitamin D metabolism of the body. Although I am unaware of the exact mechanism, it seems clear that the calcitonin/parathyroid hormone/Vitamin D/calcium balance in the body changes as people on iodine loading programs often register as vitamin D deficient when they did not previously."

    I believe this to be my case.  I tested my vitamin D levels for years and they were optimal based on Dr. Mercola's recommendations and I supplemented with D in the form of cod liver oil rarely.  Then I started taking iodine and I had such a dramatic improvement in symptoms that I knew I had been iodine deficient perhaps my entire life.  After 2-3 years of iodine supplemention I am going to get my D levels tested soon.

    Have an observation using a vitamin D light that I thought to mention.  I take vitamin D capsules and have been doing so for around 5 years.  This winter I decided that I would also use a vitamin D3 light pretty much each day in addition to taking the capsules.  I bought a light sold on Dr Cannell's sight.  I've noticed that sunlight and the artificial D3 light makes me feel warm through out the day, something D3 isn't able to do for me, at least.  And with this cold fall/winter going on right now, this 10 minutes of sunlight is a big plus!    

    Well, there might be a nice bonus from using the light.  I think I'm growing bigger, in a muscular way.  I do work out at a gym and have done so for over 1 years.  Just began the slow burn process last week.  But this muscle growth seems to have started around the time I made a conscious effort to use the indoor light or obtain some sunlight.  

    Anyway, no way to prove, and could be completely wrong about this.  Just something I've noticed as my shirts have grown tighter over the last couple months.  Weight has gone up also by a few pounds. I'm pleased.

    SMK- the test for iodine that we order in our clinic (family practice) is an iodine loading 24 hour urine test.

    patients take 50 mg of iodoral then capture their urine for the next 24 hours to see how much is excreted.

    There is a 2 week prep, though, that helps ensure the test is accurate.

    Dr. Brownstein (?) has several books on the topic. I think he recommends the load testing method in his book, "Iodine, why we need it, why we can't live without it."

    I'll be posting my comments on the IOM report soon, although this sucker is 999 pages long and taking me a while to read.  I don't think it is at all true that it focuses on "deficiency" instead of "optimal levels."  I think it is quite clearly and very explicitly focused on optimal levels.  

    The IOM claims to not have found sufficient evidence to conclude that higher levels are optimal.  Now, I do believe that there is good enough evidence to act on the hypothesis that levels should be above 30 ng/mL, and my impression so far is that there is very little data supporting an argument for >50 ng/mL as some suggest.  That said, I won't be convinced that the IOM is *wrong* that definitive evidence for greater than 20 ng/mL is lacking until I finish reading the report and look at some of the primary references.

    I do think it's important, however, to exercise the freedom to act on hypotheses.  If we needed definitive evidence for everyone we do, our familial relations and whole lives would fall apart.  Still, I think the IOM had a responsibility to assess the quality of the evidence and only solidify what is definitive into recommendations, as long as those recommendations don't preclude the freedom to use higher levels.

    In any case, hopefully I can finish this bad boy in the next week and blog about it.
